EHPECIFIGATION forming part of Letters Patent No. 531,320, datedDecember 25, 1894. Application filed January 11, 1894. Serial No.496,566. (No model.)

To all whom it may concern: 7

Be it known that we, FRANCIS L0UsAw and THOMAS E. CLARKE, subjects ofthe Queen of Great Britain, and residents of Bothwell, in the Provinceof Ontario, Canada, have jointly invented a new and us'efulDistributerfor Paris-Green, Plaster, &c., of which the following specification,taken in connection with the accompanying drawings, forms a full, clear,and exact description. This invention relates to a machine for spreadingany powdered substance, and in any desired quantity evenly overa largearea or surface, and it is particularly adapted for spreading parisgreen, &c., on potato plants, and plaster, 650., on root crops; and itconsists of the improved construction and combination of parts of thesame, as will be hereinafter first fully set forth and described, andthen pointed out in the claim.

Reference being had to the accompanying drawings, Figure 1. is a sideelevation of a machine, embodying our invention. Fig. 2. is a plan viewof same. Fig. 3. isan enlarged detail plan view of one of the perforatedholders, and the adjacent portion of its supporting shaft. Fig. 4.. isan enlarged-detail plan View of a slatted cover which surrounds eachholder. Fig. 5. is an enlarged detail cross sectional view of a portionof the holder and cover, showing one means by whiohthe cover is securelyheld at the position to which it is adjusted.

A, designates the driving wheel; B, the axle on which said wheelrevolves, and O the frame of the machine. This axle, B, maybe sup portedin bearings, formed in, or secured to said frame, 0, as preferred.

D, designates a shaft, supported in bearings, also formed in or securedto said frame, 0, as preferred.

E, designates a pulley, rigidly secured to the wheel, A; and F, a pulleyrigidly secured to the passing over the pulleys, E, F, by which motionis communicated from axle, B, to shaft, D, and attachments; or a chainbelt and sprocket wheels, or any suitable means may beused tocommunicate motion from axle, B, to shaft, D. When the pulleys, E, F,are used, one or both of them may be formed with flanges, e, to guide orlengthwise on the holder,

andholdthe belt, 'G, thereon when in operpreferably formed cylindrical,as shown in the accompanying drawings. These holders, I, are adj ustablysecured to the shaft, D, by any means found most suitable orconvenientunder the circumstances. 7

As shown-in theaccompanying drawings, the holders, I, as well as acollar, .I, rigidly secured to, or forming part of each holder, encirclethe shaft, D, and the collar, J, is provided with a thumb screw, K, sothat by tightening the latter on the shaft, D, the holders, I, arerigidly held in place to revolve with the shaft, D; and by looseningsaid thumb screw, K, the holders may be adjusted at any requireddistance apart on said shaft, D, ac-

cording to the distance between the rows of potato plants, root crops,&c.

N, N, designate endless bands, encircling the holders, 1, and secured tosaid bands, N, are the slats M, M,-formed'with extended portions, m, m;and there are the same number of slats as there are longitudinal rows ofperforations, O, in the holder, I, and the slats are the sameproportionate distance apart as are said perforations, 0, so that byadjusting said endless bands, N, N, around the circumference of saidholder, I, the slats, M, maybe adjusted to partly or completely coverthe perforations, O, in said holder. This regulates the feed or thequantity of powder passing out of said holders, I, or these endlessbands, N, and slats,M, may be in the form of a sleeve, cover orsupplemental cylinder formed with slots, corresponding to the openingsbetween the slats and said endless bands, and they may-be adjustedaround the circumference I, as preferred. d, and b, designate slots inthe holder, I," and one of the endless bands, N, respectively. P,designates a screw threaded bolt, one end of which is rigidly secured tothe holder, I; and the slot, b,,in the endless band, N, is formedelongated, through which slot, the screw threaded bolt, P, projects; andR, is a thumb nut, which is turned on the bolt, P, which thumb nut whentightened, rigidly secures and binds the slatted cover on the holder, I,in any desired position to which it may be adjusted; and this bolt, I,may be secured to the side or end of the holder, as preferred.

The operation of this invention is as follows: The holders, I, are firstadjusted the required distance apart on the shaft, D, so that they willcome directly over the potato plants, if it is desired to use themachine as a paris green distributor. After adjusting the holders, I,the required distance apart, the slots 1), and d, in the cover andholder respectively, are adjusted opposite one another, through whichopenings, the holder is filled with the paris green. Then by adjustingthe cover until the opening, b, is opposite a solid portion of theholder, the opening in the latter willbe completely covered by the solidportion of the band, N, as shown in Fig. 5, to completely prevent theescape of the contents of the holder at the opening, (1. If it isrequired to distribute the paris green over a surface equal to the fulllength of the holder, the slats, M, together with their extensions, m,are adjusted to come between the longitudinal rows of the perforation,O, of said holder; and if it is found that this spreads the paris greenover too wide a surface, the slats, M, are adjusted around the holder,until the extended portions, m, only, are adjusted over the perforationsin line with them, these extensions, m, closing only the endperforations independent of, and without interfering with the centralperforations; after which, the holder may be adjusted, so that thecentral perforations will come over the desired surface on which it isrequired to distribute the paris green. Then by grasping the handle endsof the frame, the machine can be readily and easily moved forward on thewheel, A, and as the latter revolves, the pulley, E, also revolves, aswell as the pulley, F, and shaft, D; and the holder, I, being rigidlysecured to the shaft, D, said holder also revolves and agitates theparis green held therein, to deilver it freely and evenly, and in anydesired quantity through the perforations, 0, on to the potato tops, orany powdered substance contained in the holder, I, over any surfacerequired.

Having thus described our invention, we claim- An insecticidedistributor consisting of a rotatively mounted perforated cylindricalholder having-at one end a screw and a filling aperture and at the otherend a circumferential ridge or flange, in combination with a perforatedcylindrical cover closely fitting said cylindrical holder and adapted toabut at one end against the flange thereof, the other end of said coverhaving a slot adapted to permit the passage of said screw and also to bebrought into register with the filling aperture, and a nut on said screwwhereby when adjusted, said cover may be locked in position,substantially as set forth.

In testimony whereof we have signed in the presence of the twoundersigned witnesses.
